To all whom it may concern:

Be it known that I, LOUIS J. CHAPPELLE, a

citizen of the United States of America, r

siding at Green Bay, in the county of Brown and State of Wisconsin, have invented certain 'new and useful Improvements 1n Door- Locks, of which the following is a specification, reference being had therein to the accompanying drawing.

The invention relates to improvements 1n doors, and particularly in double doors, such as are employed for garages, warehouses, and similar buildings.

It is an object of the invention to provide double doors, hingedly arranged and adapted to be openedor closed u on the corresponding movement of once said doors.

Another object of the invention embraces the provision of means for securing. the doors in any position, so that accidental closing of the doors when aj'ar is eifectively prevented.

It is a further object of the. invention to provide means for securing the doors in any position, which means arecontrolled by the lock of the doors.

Still another object embraces the provision of means for preventing engagement between thelocking rods of the door and the door frame.

It is also an object of the invention to provide certain details of construction and arrangement tending to increase the usefulness and general desirability of doors of the.

character described.

To the accomplishment of the objects stated and others that will become apparent upon perusal of the following specification, the invention then is predicated on the means described hereinafter and specifically pointed out in the appended claims.

The annexed drawings and the following description Set forth in detail certain mechanisms embodying the invention which, however, constitute but one of thevarious ways in which the principle of the invention may be utilized.

In said drawin -Figure 1 is a slde view with parts in action, disclosing the door in closed position and 1ts associated and cooperating parts.

Fig. 2 is a front elevation of the lockin open position.

:Fig. 3 is a view similar to that ofFig. 2, with the lock in closed position.

4: is a top plan view showingthe doors in closed position.

Fig. 5 is a view similar to Fig. 4, with the doors in open position.

Fig. 6 is an end vew of a guide secured to the ceiling and receiving a lock connected to the double doors.

Referring to the drawings and particularly to Fig. 1, 1 and 1' designate the double doors which are adapted to close the opening 2, through which entrance may be had to the interior of the building, which is equipped with the floor 3 and with the ceiling 4;. The doors 1 and 1 are secured to the jambs or frame members 5 and 6 respectively, by means of hinges of known construction, and are capable of being swung from the closed position, as shown in Fig. 4, to the open position, as indicated in Fig. 5. At-the front edge of the door 1 locking rods 8 and 9 are arranged in vertical alinement and extend through a vertical bore in the door 1. l The rods have a limited vertical travel for the purpose of entering sockets 10 and 11, res ectively arranged in the upper transverse beam of the door opening and in the floor 3. The locking rods 8 and 9 may be shifted from the socket en gaging position into thefretracted or releasing position to permit swinging of the door from open into locked position and vice versa. An opening 12 is arranged in the door 1, into which the locking rods extend and terminate in heads 13, 14, respectively. Levers 15, 16 are respectively connected .to said heads and are pivotally supported as at 17 and 18. The free ends of the levers 15, 16 bear against a cam 19, arranged on a shaft 20, which projects through side plates 21, 22, closing the opening 12 of the door. The shaft 20 terminates at both ends in knobs 23, whereby the cam 1,9 may be rotated t o 0ccupy a vertical or an intermediate pos1t1on; A spring 24 engages the levers 15, 16 adJacent to the pivot 17, 18 in order to normally hold the free ends together. Within the opening 12 a bl0ck 25 is slidably arranged and controlled by a key inserted through the key-hole 26. The operation of. the lock can be easily recognized from the arrangement ofthe parts shown in Figs. 2 and When the block 25 is in the pos1t1on shown in. Fig. 3, the cam 19 forms an acute angle withthe horizontal plane,and consequently the free ends of the levers 15-, 16 are under 7 one another, whereby the rods 8 and 9 are placed in the socket engaging position and thus the doors are locked. In order to permit withdrawal of the locking rods 8 and9,

the sliding block is shifted to the right hand side, as viewed in Fig. 3, until it occupies the position shown in Fig. 2, which movement is accomplished with the insertion of a key in the hole 26' and appropriate turning of the key. In this position the shaft, 20 maybe rotated by actuating the knobs 23 to effect a spreading of the free ends of the levers 15, 16, whereby the looking rods 8 and 9 are withdrawn from the appertaining sockets, so that the door 1 may be swung from the closinginto the open or an intermediate position. The doors 1, 1'

are each equipped at the upper end and adjacent to the free edge thereof with a bracket 27, equipped with an upstanding pintle 28, which is adapted to receivethe head 29 of a link 30. The links 30 of the doors are connected at the outer ends to a block 31, formed to slidingly fit in a guide 37 of appropriate length to incase the block 31 throughout its movement. The guide 37 is secured to the ceiling 4 and insures a simultaneous opening of thedoors l, 1 when either one of them is moved. Secured to the bracket 27 of the door 1 is an arm 32, which termmates 1n a semi-circular member 33,.

provided with a plurality of spaced teeth 34, adapted to receive in the grooves formed between the teeth the-rod 30 so as to lock the same and thereby prevent movement of the doors in either direction. The arm 32 at its other end has a pin and slot connect1on, as at 35, with the locking rod8, so that the engagement or dissengagement of the member 33 with the rod 30 can be, controlled by the rod 8. The actuation of the doors and their locking in the closed, open, or intermediate position is thought to be understood from the preceding description.

T The doors 1,1 in the closed position shown in Fig. 4 have the locking rods 8, 9 arranged in recess engaging: position, whereby rotation at the shaft 20 by manipulation of the knobs 23 is impossible. To open the door the key is inserted through the hole 26 and the sliding-block 25 is shifted into the position shown in Fig.2, whereupon the knob 23 is turned to bring the cam memberinto 7 vertical position, whereby the free ends. of

the levers 15, 16-are spreadf This results in bringing the heads 13, 1&1 of the locking bars 8, 9 1n proximate position and releasing the rods 8, 9 from their sockets, so that the door 1 may be movedintofthe open or into an intermediate positionflwjictuation of the door 1 is transmitted by'the to the actuated by masses 1 door 1. When the doors-occupy the desired,

position, the knob 23 is again turned to permit'the spring 24 to spread the heads 13, 1d of the locking rods, whereby the arm 32 is actuated to bring the cam 33 from the normal disengaging position shown in dotted lines in Fig. 1 to the position shown in solid lines in said figure. This 'causes the rod to be received within a groove formed by two adjacent teeth. As is indicated in Fig. 1, the recesses. 10 and 11 are formed with extensions 36,.whereby engagement between the rods 8, 9 with the frame of the door is prevented.

The drawings show the preferred embodiment of the invention which, of course, is merely indicative of the principle underlying the invention. A considerable number of changes-and alterations will readily suggest themselves to those versed in the art, and I therefore do not confine myself to the details shown in the drawing, but wish to avail myself of any departures which fairly fall within the scope of the invention as'indicated in the appended claims.
